It's my first visit to Prague , I'll be here for three days for a conference , then I have a day on my own to do some sightseeing before I head back home . What do you suggest I see when I'm here ?   There are many interesting places you should be sure to see . One problem is transportation , however . Because the city is very old , the roads are narrow and congested . If you only have three or four days to visit , you don't want to spend them waiting in traffic in a cab . I suggest you take the subway .   The subway ? But is there a subway station next to my hotel ? I have to go between the conference center and the hotel several times a day ...   No worries , there's a subway station at the conference center itself , and a shuttle from your hotel to the conference center that takes only 5 minutes . When you do your personal sightseeing , you can first take the shuttle to the conference center , then hop on the metro .   Is it expensive to ride on the underground ?   You can get a daily pass that will allow you to travel unlimited for the whole day for about 6 dollars . Otherwise , you can pay by trip , which is about 50 cents to 2 dollars each trip , depending on how far you go .   Is it easy to get lost ?   No , no ... . it's very hard to get lost . There are two lines , one that goes in a circle , the other that is straight . If you get lost , there are always subway attendants that can help you find your way .
